+This is GRBL 1.1 ported to the LPC1769. 
+It can run on the following boards:
+- Smoothieboard
+- Cohesion3D Remix and Mini
+- MKS SBase
+- Azteeg X5 
+
+SKR boards don't work, because pin mapping is messed!
 
 **Usage notes:**
 * This uses a different usb-serial driver than Smoothieware. Windows 10 should recognize it automatically.
